ABSTRACT

Pharyngitis remains to be one of the most common childhood illnesses around the world. Majority of the pharyngitis are caused by viruses, but about 20%–30% of cases in children are due to group A Streptococci (GAS), which is a significant cause of mortality and morbidity in the developing countries. The present study finds out the prevalence of acute pharyngitis caused by the GAS. A total of 156 throat swab samples were collected and inoculated on blood agar then, these isolates were identified by the standard microbiological procedures. Group A Streptococci were isolated from 14.7% (23/156) of pharyngitis patients and 8.3% (3/25) of the healthy carriers. Among the GAS isolates, 26.1% (6/23) were from males, whereas 73.9% (17/23) were from females. The highest prevalence of GAS rate was found in 4-9 years 60.9% (14/23). All the isolates were 100% sensitive to penicillin, whereas 21.7% and 8.7% isolates were resistant to tetracycline and erythromycin respectively.
